SPRING-WHEEL.

Specification of Letters Patent Patented June 23, 1914.

Application niea May 3, 1913. 'sei-iai No. 765,368.

To all whomy it may concern:

Be it known that I, JAMES W. CLIFTON, a citizen of the United States,residing at Macon, in the county of Bibb and State of Georgia, haveinvented a new and useful SpringWheel, of which the following is aspecification.

My invention relates to new and useful improvements in spring wheels.

The `primary object of the invention is the provision of a substantialwheel which is resilient and will overcome excessive jarring.

A further object of the invention is the provision of a wheel of thischaracter in which the spring spokes may be easily removed and replaced.

Vith the foregoing and other` objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of what is claimed without departing from the spirit of theinvention.

In the drawings: Figure 1 is a sectional view on the line A-A of Fig. 2with parts broken away. Fig. 2 is a sectional view on the line B-B ofFig. 1. Fig. 3 is a side elevation of the side plate. Fig. 4 is a viewof the hub partly in section. Fig. 5 is a sectional view of theintermediate rim.

In the drawings the numeral 1 indicates the rim; 2, an intermediate rimand 3, a hub. Flanges 4 are formed integral with the intermediate rimand receive the rigid spokes 5 which are between the outer rim and theintermediate rim. On the inner periphery of the intermediate rim areformed the socket members 6 having the slots 7 and as clearly shownthese socket members are formed on each side of the rim. Ball races 8are formed on the side faces of the intermediate rim as clearly shown inFig. `5 and in these ball races are received the balls 9.

Sockets 10 are formed in each end of the outer periphery of the hub,said sockets being provided with the slots 11 as clearly shown in Fig. 4of the drawings. The ends of the hub are squared at 12 and plates 13 aremounted on the squared ends of the hub. These plates are of greaterdiameter than the intermediate rim. The plates are provided with theflanges 14 and may also be provided with the flanges 15 to receive abrake band. A flexible strip, preferably of rubber, 16 having a wireband 17 secured thereto is secured to each plat-e 13 and as will be seenengages the plate and the flanges 14. This flexible strip also engagesthe intermediate rim as shown in Fig. 2 of the drawings and prevents theaccumulation of dust or other substance on the interior of the wheel.The ends of the hub are provided with the' usual ball bearings 18 whichprevent friction.

Between the intermediate rim and the hub I provide the spring spokes 19which are of the shape shown in Fig. 1 of the drawings. The spokes areenlarged at the ends as shown at 2O and these enlarged ends of thespokes are received in the socket members formed on the intermediate rimand in the hub. The spokes pass through the slots formed in the socketmembers and as shown in Fig. 2 of the drawings there are four rows ofthese spring spokes, there being two rows on each end. There are twicethe number of socket members formed on the intermediate rim as there areformed in the hub which will necessitate the ends of two spring spokesbeing received in each socket of the hub. The socket members of theintermediate rim only receive the end of one spoke. By having the springspokes of the shape shown one end of the spoke is held in a socket onone side of the hub and the opposite end of the spoke is received in asocket on the intern mediate rim at a point opposite the opposite sideof the hub. The spring spokes overlap in the manner indicated in Fig. 1and will take the strain from the wheel in any direc- Lion.

The plates 13 close the ends of the socket members to prevent theaccidental displacement of the spring spokes. As is clearly shown inFig. 2v of the drawing the balls 9 engage on the inner face or surfaceof the plates 13 and thereby overcome any friction.

Having fully described my invention what I claim as new and desire tosecure by Letters Patent is A spring wheel comprising a rim, a hub andan intermediate rim, rigid spokes b`e.

tween the two rims, sockets formed on the inner periphery of theintermediate rim and the outer periphery of the hub, and spring spokesbetween the intermediate rim and hub, the ends of two spokes beingreceived my own, I have hereto affixed signature 1n each socket on thehub and the spokes eX- ln the presence of two Witnesses. tending inopposite directions around the hub and the ends received in cireumferen-JAMES V CLIFTON' 5 tially spaced sockets in the rim at a point onVitnesses: the opposite side of the hub.
